Hi all,

I have a FileListBox that shows the *.txt files and a user has in a directory. When a user highlights the file they want and clicks a Command button, user can edit that file and save it as newfile.txt

Here are the list of a text file :

:25:186350587

:61:1006150615DR500000000,NTRF//

User want to insert all line that contain :25: with two zero, so it would be like :25:00
Can anyone help me with the code in Visual Basic?

Thanks
Andi
